scilearner Posted February 15, 2011 Share Posted February 15, 2011 This enables them to make haemoglobin. How? They still require mRNA, they don't have a nucleus. So how are ribosomes going to help? Thanks Link to comment Share on other sites More sharing options...
Blahah Posted February 15, 2011 Share Posted February 15, 2011 Erythrocytes do have a nucleus during erythropoiesis until they reach the reticulocyte stage. The mRNA is generated during the developmental stages before the nucleus is expelled, and the quantity in the cell reduces with the expulsion of the nucleus but, as I understand it, is not entirely diminished. What remains can, with the residual ribosomal RNA, be used to maintain the required amount of haemoglobin. Link to comment Share on other sites More sharing options...
